Neuroterus niger variety pattersoni, new variety
bisexual form pattersoni, new form

GALL. — Circular, not elongate, very slightly smaller than nigripes, with more well-defined boundaries and without a trace of a central point on the upper surface. On Quercus stellata (fig. 43).

RANGE. — Texas: Austin (Patterson coll.).

Dr. Patterson, for whom this variety is named, collected and bred the type material. He states that in 1921 the gall first appeared March 10, the adults beginning to emerge on May 7. Dr. Patterson sent me records (a year ago) of breeding 453 females and 450 males, making the important observation that a single leaf of galls usually yields only a single sex of the wasp. The detailed record of these observations I should leave for Dr. Patterson to publish. It would appear that the agamic females are of two sorts, either female- or male-egg-producing. What is evidently the agamic form of pattersoni is described in the following paragraph.
